SPEGFIGATQN forming peri of Letters Patent No. 664,865, dated January l, 1901. 4dpplioation tiled iey 3l, i898. Renewed July 27, 1900. Seiial No. 25,049. (No model.)

To @ZZ wil/om, :it may oon/corio:

Be it known that i, Devin E. HOWATT, a eitizen of the United States, and n resident of Rosljfii, in the oonnty of Nassau and Sta-teef New Yo have invented oei-tain new and useful improvements iI Sectional Weterieetei's, of which tbe followingisespeeiiioa tion.

The invention rela-tes to improvements in sectional water-beaters; and eonsistsiu the novel features and combina-tions heieinafter described, and pei'tionlaily pointed out in Athe claims.

e obere-eter of heaiersdesoiibed and claimed in the Lettere Patent of the United States heietoi'oie greetedto nie and numbered, respeetiveiyi, odnly 1,1890,a.ud 459,095, of September 8, 189iend its object is to produce n heetei which shell be more efficient end economical in operation than the earlier -heeteis of the elass to wbieh it relates and which also shall be of superior mechanical oonsiinetion end less expensive of produ@- tion.

bevo embodied the invention, es hereinai r `ly explained, in e bester composed iedividnei Vei'tioei hollow communicotiner sections substantially corresponding with one enothei and arranged side by side to form a beater of the desired length, eee-hseotion be- .ing complete in itself and the bank ofseotions being bound together between twoeud sections by bolts and superimposed over e suitable eshpit. Between the lower portions o2.' iegs of the several see-tions is formed the mein ooinbuetion-ehmnber, end through the upper portions of sections ere foi'ined three longitudinal conduits o1' fines, all being side by side .and effe-:ding e passage to the exit-pipe for the smoke, gases, and other products of combustion asoendingfi'oni the furnace oi mein combustionehnmbei. The i' per central portions of the said sections te somewhetieised and nre Vfoinped with eitudinel opona through their side feces nder that the interior weter-ehembei's of t severa-il sections may be brought into dieoinfnulf Ltion with one another, and ioised no. ion of the nope? part ol" the s ne reeeiiies tbe outlet-pipes for the we tei from 'the beater, the inlet or return pipes The invention pertains more especially toA `"the beet inward to the water and compel o more eiioient oiroulation of the water.

The invention will be thoroughly under stood from the detailed description hereinafter presented, reference being had vto the accompanying dmwings, in whieh- Figure l is a perspeetive View oleJ com plete sectional water-beater Constructed in accordenee with and embodying my invention. Fig. 2 is e horizontal longitudinal section of seme,

leken eentraily through the three smoke lines. Fig. Sis an inner1 faoe View of one part of one of the hollow sections. Fig. is evertioel section of a. complete hollow section on the line e of Fig. 3. Fig. 5 is :i transverse section of seine on the dotted line 5 5 of Fig. Fig. 6 is e, like section of seine on the line o of 3. lig. 7 is im inner fece View oi' the other peri'. of one of the hollow sections. Fig. 8 hollow sections on the dotted line 8 8 of Fig. 3, and Fig". 9 ie a perspective View of one of the hollow sections.

In the drawings, A designates the individual hollow sections .intermediate the end soetioIi-s, wbieh are indica-ted by the letters B C, respectively, and seid sections, as shown in Figs. l and 2, are arranged side by side over-eJ n suitable aslbpit l) to form the'oomplete wetenbeatex", the bodyr of which above the ash-pit being compose-:l of a bank of seid sections eX- tending transversely over the ashpit and forming between their lower outer portions or less the sides of the {ire-box oi' combustiononani ber E, eeoess to which may be had et one o1 both ends of the heater by means of e. suitable dooi` or doors F. The bank of sections (denoted by the letters A B C) are iirmly seouied "together by the bolts G, es hereinafter eX- pleined.

The construction of the sections A may be fully understood on reference to Figs. 3 to 9, inclusive, in which it will be seen that each e trensveise section of one oi the IOC section is formed of the 'two auxiliary sections -or parts H L'which when brought together forni a hollow section adapted to hold and permit the circulation of the water to be heated. The part H of the sections A is of receptacle shape, being formed of the face and longitudinal iianges J, and the part i of said sections is in the nature of a face-plate having narrour longitudinal flanges K and itting within the flanges J of the part H,a rust or other sui*- able and convenient. joint being formed between the contacting portions oi' the said parts H I. The angesJ K of the parts H i of the individual hollow sections extend aiong the entire edges outlining said parts H l, and said parts H I are also formed with the longitudinal flanges L M, which engage one another, as do the anges J K, and form sections of the three iiues N O P, extending longitudinally Athrough the upper portion of the heater and leading to the final exit or smoke pipe Q. The lues N O Pare on the same horizontal piane, and the side tlues N P are closed at one end and at the other endare brought into com in unient-ion with the central flue O by means of .the bonnet R at apoint farthest removed from the smoke-pipe Q. T he outer portions of the hollow water-sections have the faces S at their front and rear sides, and these faces S when the said sections are brought togethercontact with one another, and saidsections along their middle portions over the tire-box and below the central flue O are depressed or set inward at their front and rear sides, and preferably on downWardly-converging lines, to form vertical transverse heat-fines T between said hollow sections, said lines T at their upper p0rtions communicating with the-side longitudinal fines N i) and being prevented from having communication with the central longitudinal due O by reason of the face-to-iace Contact of said sections entirely around said 'centralflue U, the said sections heing so formed as to permit and insure this result. It will thus he apparent that the gases and other products ascending from the fire-hon or combustion-chamber will pass into the heatfiues T and after spreading over the front and rear surfaces of the holiow sections A will enter the side longitudinal nes N and pass through the same to the central flue O, through which they will pass to the exit or smoke pipe Q. The heat from the {ire-box is thus compelled to do its maximum duty before reaching the smoke-pipe Q., and greater eliiciency is thus secured in the heater, since the ascending heat is compelled, with its maximui'n effect, to pass laterally over the front and rear faces of the water cells or chambers to reach the, iiues N P instead of being permitted to act upon its natural tendency to ascend at once and pass directly into the central iue 0, leading to the exit-pipe Q. The inner faces of the parts H I of the hollow sections are provided with ribs V (or equivalent means, such as studs WV) to conduct the heat inward into the water-oeils, the more quickly senese and economically to heat the Wateranfl conipel its proper circulation. At the lower side portions or legs of the hollow sections areV formed the corresponding iongitudinal alined r apertures X, which are in the face-to-iace contacting portions of said sections and afford means for the water to pass from one to another of said sections at points adjacent to the inlet-nozzles Y, formed in someo'f said sections, for receiving the pipes (not shown) by Which the water is fed or returned to said sections at opposite sides of their lower portions. rThe end sections B C at their outer faces have small apertures in liue'with the aforesaid apertures X, and through those small apertures and the said apertures pass the lower bolts G, securing said sections 1o gether, the diameter of the apertures X being greater than that of the bolts Gr, so as not to permit the holts G to interfere with the circ-ulation of the Water'frcm one to anotherof said sections. f

Above' thecentral iue O the sections AB C are raised or dome-shaped, as denoted ata, and through the contacting faces of this portion oi these sections are formed the longitudinal aline-d apertures l), which form Vmeans for the passage of the. water from one section to another adjacent to the points Where someV of the sections are provided with the nozzles dor thecoupling thereto of the outlet-pipes (not shown) for thehot water from the heater; Through the apertures h andthesnialler aper# tures in the front and rear faces of the heater passes the upper securing-boltG, Whose di-A IOC alneter is less than'the diameter of the said apertures l), so as .not io close the saine. In view of the fact that the apertures b permit 'water communication from one section A to another aiong the dome orhead portion a it is unnecessary toprovide. each of said sections with the elitist-nozzles d, and, iikewise, since the apertures X establish Water coniinunicaiion between the lower portions of the hoiiovv sections it is unnecessary to provideY ail the sections with the inlet-nozzles Y.

The exterior outline of the sections A B C is of importance in that the vertical outer portions of saidv sections above their lower ends turn outward and then upward, as

shown, both Within and Without the heater, and thereby increased water capacity is created in the sections, and the fire-box is given greater breadth or lateral extent with increased eiiciency.

The operation of the heater hereinbefore described will probably be understood from the explanations above given, 'and hence but brief further-description of the saine is required. The sections A B C heing in position and secured by the boit-s G, 'the rire will he started in the fire-hon E and the water per initted to enter the iower portions of said sections through the nozzles Y and apertures X and to escape from the upper portions of said sections through the apertures b and nozzles The gases, heat, and other products asizo . poriooe ol" he .iffye beer iieseri'eei es Y' come ini-o eoiieei wii er; m ue noi he understood that 'bile-se faces neeeeseriiy come imo physical touch with one mother, since e. eyer of eebestos may be oed het-Ween iiiei1i,eudit may be preferred i provide the feeee with ribs x, which coming; gogenher will leave small speees the belier: sections to receive the feeoe.
